Well when people talk about "vegetables" Faye they normally mean leafy veg, root veg and maybe some that are botanically speaking fruits (tomatoes etc)
None of these contain much protein. They also lack fat soluble vitamins.
A vegan diet that only contained "vegetables" might keep an adult alive but would not support healthy growth of a child - they need fats and proteins that could,( if you were careful and had the luxury of choice), be obtained from nuts, grain, pulses etc.

- just to throw the cat into the vegetarian pigeons. Is it not the case that in order to be healthy on a vegetarian diet you need to have a very particular mixture. Carbohydrates are no problem as rice, wheat etc cheap staples. But to get enough protein you have to have a seed of some kind that complements the amino acids in your staple - otherwise, instant protein deficiency. And without a fair quantity of a good range of vegetables you are likely to be short on vitamins such as A (and D in a cold climate). Animal foods (whether fish, sheep or tarantula) are concentrated forms of complete protein and fat soluble vitamins.
